Gynecomastia

A common disorder known as gynecomastia causes enlarged male breast tissue. Males of all ages can exhibit it, but it is most common during puberty, the infant stage, and later life. Gynecomastia can have a variety of causes, but the most prevalent one is a testosterone and estrogen imbalance.

Under the nipple, gynecomastia appears as a button-sized protrusion. If you press on the area, you might feel this or be able to see it as a breast bump. The lump may be touchably sore and may move readily within the breast tissue. Breast growth and breast lumps can affect one or both breasts. Between 50 and 65% of boys and men worldwide suffer from gynecomastia.
